Casas was the only athlete in the field to come back sub-28, splitting 27.74, as he jumped up from fifth at the 50 into second at the finish, producing the second-fastest swim of his career in 54.69. His best time was set at last summer’s Nationals in 54.51.
Casas is one of 41 junior swimmers selected to compete in two international events for the USA Swimming’s 18 & under team. The Mare Nostrum will take place in Canet-en Roussillon, France, from June 11-12 and Barcelona, Spain, from June 15-16.
Casas is coming off a standout freshman campaign, becoming the third A&M freshman to score in individual events at the NCAA Championships and the first to do it in individual events (200-yard individual medley and 200 butterfly). He was named honorable mention All-American in the 200 IM and earned SEC all-freshman status in the 200 backstroke.
